Adams began his coaching career at the St. Paul's School, where he served as the head lacrosse and football coach from 1951 to 1953. Against
Duke, Adams played 33 different players in a failed attempt to hold down the score. In 1961, in the first nationally televised lacrosse game, Army upset
Navy, 10–8, to capture a share of the national championship alongside the Midshipmen. That season, Adams was awarded the
F. Morris Touchstone Award as the USILA Coach of the Year. In 1969, the Cadets again defeated Navy to clinch a share of the national co-championship in Adams' final game at Army. The result was a 14–4 rout at
Navy–Marine Corps Memorial Stadium in front of 16,056 spectators. After his daughter graduated from high school in 1969, Adams wanted to work close to where she attended college. During his tenure there, he led the Cavaliers to 12
NCAA tournament appearances and four semifinals appearances, while they twice finished as runners-up. Adams was inducted into the
National Lacrosse Hall of Fame in 1975. ==References==
